Comparison of Emergency Cholecystectomy with Delayed Cholecystectomy After Percutaneous Transhepatic Gallbladder Drainage in Patients with Moderate Acute Cholecystitis

Abstract

Introduction: Patients with moderate (grade II) acute cholecystitis patients, as defined by the 2013 Tokyo Guidelines, were retrospectively compared with respect to emergency cholecystectomy (EC) and delayed cholecystectomy (DC) after percutaneous transhepatic gallbladder drainage (PTGBD) to determine the better treatment strategy.

Methods: Forty-nine of 103 patients with PTGBD and 47 of 54 patients with EC were assessed for eligibility from January 2013 to January 2017. Patients with the following conditions were included: (i) moderate (grade II) acute cholecystitis diagnosed by the 2013 Tokyo Guidelines; (ii) no common bile duct stones; (iii) no atrophic cholecystitis; (iv) no decompensated liver cirrhosis and massive ascites; (v) no diffuse peritonitis; (vi) surgeons are professors or associate professors; and (vii) PTGBD is not the only procedure for the patient defined by clinicians. The preoperative characteristics and postoperative outcomes were analyzed. PTGBD was performed by experienced interventional radiologists and cholecystectomy was performed by professors or associate professors.

Results: Patients in the EC and PTGBD + DC groups had similar demographic, clinical, preoperative laboratory, and imaging characteristics. Both PTGBD and EC resolved the cholecystitis quickly. Compared to the PTGBD + DC group, EC patients had more intraoperative bleeding (101 ± 125 mL versus 33 ± 37 mL, P = .003), longer duration of postoperative abdominal drainage (9.0 ± 12.9 days versus 3.4 ± 2.1 days, P = .041), more patients converted to open cholecystectomy (OC; 19.1% versus 4.1%, P = .021), more OC patients (14.9% versus 0%, P = .005), more patients with gangrenous cholecystitis (40.4% versus 8.2%, P < .001), more cholecystitis patients with perforation (12.8% versus 0%, P = .012), a higher incidence of respiratory failure (14.8% versus 2.0%, P = .029), more admissions to the intensive care unit (ICU) (21.3% versus 2.0%, P = .003), and longer postoperative hospital stays (8.2 ± 3.2 days versus 11.6 ± 4.6 days, P < .001) in the PTGBD + DC group. In addition, there were statistically more OC patients (63.2% versus 14.3%, P = .001) in the nonbiliary surgeon group than the biliary surgeon group.

Conclusion(s): In patients with moderate (grade II) acute cholecystitis, PTGBD and EC were highly efficient in resolving cholecystitis. DC patients after PTGBD had better outcomes with a lower rate of OC, less intraoperative bleeding, shorter duration of postoperative abdominal drainage, shorter hospital stays after cholecystectomy, a lower incidence of respiratory failure, fewer admissions to the ICU than EC, and reversed the pathologic process affecting the gallbladder. The total postoperative hospital stay was longer in the PTGBD + DC group.
